sofirn 3000mah 18650's - Good or bad?

[MyUsernameTX]

I got a bunch of sofirn D25L headlamps, and they all came with 3000mah 18650's. I did a charge test on my Opus charger, and they all reported 3000mah +/- but one that reported 3400mah

The look like these: https://www.sofirnlight.com/products/3000mah-18650-batteries

Are these cells generally trusted? Figured I'd ask before my curiosity gets the better of me and I unwrap them

3400mAh is desirable.. Could be one cell is upgraded from Sofirn?
Before unwrapping I'd ask Sofirn exactly what cell is inside, they're fairly quick to reply.
Just my 2 ct..

I have several of these batteries as well one from Wurkkos that appears to be identical. I have never had any issues with them.
